2 disc install, can't umount 1st to continue install with 2nd

redbeansnrice · 09-01-2004, 02:36 PM

There is a database app I'm installing from 2 discs. The first disc has the program and part of the data, the 2nd disc has the rest of the data. It gets to a point where it tells me to put in the 2nd disc, but it won't let me umount the drive because the app still has it open.
I tried umount /mnt/cdrom but the device is busy.
If the app shuts down at this point, it says it needs the 1st disc when I try and run the app. Not a very sofisticated piece of work.

Anyone know how I can switch the discs?

Thanks in advance.

Are you sure it's the app that still has it open and not another process that is preventing the umount? KDE is known to not let go of a device even when you're not using it. Do a "lsof" to see which files are being used.

Either you can copy the contents of the 1st or the 2nd cd to your hd and run only 1 cd. I'd copy the 1st and start the install from hd, then, when it asks for the 2nd cd, just load it.

"lsof" ... command not found
copy to hd ... I'll give it a shot, but i don't think I have the option to navigate to a file...it auto-searches the cdrom drive for the disc 1 data

When I've had 2 or 3 disks install, I've done this:

Open two terminals:

Terminal 1)

$ su
<password>
# mount /mnt/cdrom

Terminal 2)
$ cd /mnt/cdrom
$ ./install

When prompted for disk 2:

Terminal 1)
# umount /mnt/cdrom
<swap disks>
# mount /mnt/cdrom

You may need to copy the installer script / program to /tmp and run it from there

Good luck!

What does pwd comand says? If it is /mnt/cdrom you'll have to "cd .." before trying to unmount CD.

You should never change directory to the mount point, thats generally the primary reason you cant unmount when you need to insert the next disk, your shell is sitting on the mount point.

eg.

this is wrong

mount /dev/cdrom /cdrom
cd /cdrom
./run_some_installer

this is correct

mount /dev/cdrom /cdrom
/cdrom/run_some_installer
